Rutland, Sterling, and West Boylston.
The 4,135-acre reservoir was built between 1897-1908
by damming the South Branch of the Nashua river. Water was sent
via an aqueduct to the Weston reservoir. It now receives some of
its water from Quabbin Reservoir and still supplies the Boston area.
programs and field trips are offered to schools and groups in
or bordering the watershed areas, and to MWRA service communities.
Topics range from water's behavior and physical properties, watersheds,
cultural and natural history of the watershed areas
Things to know before you go
The primary purpose of DCR water and surrounding lands is drinking water supply. Public access, therefore, is carefully regulated and controlled to protect over 2 million people’s source of drinking water. State regulations require all entry and exit through gates or other designated areas only. Anything that could pollute the water supply system, such as litter or refuse of any sort, is prohibited. Please observe restrictions on recreational activities. Direct water contact activities, such as swimming and wading, are strictly prohibited by regulation.
Dogs are not allowed on any DCR property associated with Wachusett Reservoir.
Please refer to the specific rules and regulations available below.
